Open Source Spacelift Alternatives

Spacelift is an infrastructure automation platform for Terraform, OpenTofu, Pulumi, CloudFormation, and Ansible that provides a collaborative workspace with policy-as-code, drift detection, private runners, and audit logging. It enables infrastructure teams to review changes before apply, enforce compliance policies, manage secrets securely, and track every infrastructure mutation across cloud environments. Its module and stack management features help large organizations govern IaC at scale.

Teams consider open source alternatives to Spacelift to self-host their infrastructure automation layer, reduce costs for large numbers of managed stacks, and integrate more directly with existing security and compliance tooling. Open source IaC orchestration tools offer comparable workflow automation, policy enforcement, and state management capabilities deployable on-premises or in private cloud environments.
